July Public Observing - Total Solar Eclipse Saturday, July 29, 2017 9:00 PM The Total Solar Eclipse of August 21st

A solar eclipse occurs when the Moon crosses over the face of the sun and the moon’s shadow strikes the Earth's surface. This summer’s total solar eclipse will cause one of the most majestic natural wonders that most people will see during their lifetimes, and Illinois is the place to be to see it.

In addition to our presentation, we will have a laser-guided sky tour and telescope observing.

Perseid Meteor Watch Friday, August 11, 2017 9:00 PM This will be only a 90-minute event due to the moon phase. After the waning gibbous moon rises, the possibility of observing meteors drops precipitously. I suggest scheduling from 9:00 to 10:30 PM only, but start earlier if you want a campfire and s’mores etc. With such a short time for observing, I don’t want to give a talk (which many will have heard before anyway). I’ll arrive and set up around 8:30 PM assuming the sky is clear. The event will be cancelled in the event of a partly to mostly overcast sky.

August Public Observing - Moon and Sun Saturday, August 26, 2017 8:00 PM Moon and Sun

Our moon, the brightest object in the sky after the Sun, is the sole natural satellite of the Earth. Learn about the moon's relationship to, and impact on, the Earth, including a review of the recent total solar eclipse. Some of the interesting features on our nearest celestial neighbor will be presented also.

In addition to our presentation, we will have a laser-guided sky tour and telescope observing.

An emission nebula is a nebula formed of ionized gases that emit light of various colors. The most common source of this ionization is high-energy photons emitted from a nearby hot star.

In addition to our presentation, we will have a laser-guided sky tour and telescope observing.
